Quadrilateral abcd is an isosceles trapezoid. if ab || cd, ab = m + 6, cd = 3m + 2, bc = 3m, and ad = 7m - 16, solve for m. a.) 2 b.) 3 c.) 4 d.) 5

C.) 4

Step-by-step explanation:

we are given ABCD is an isosceles trapezoid

AB || CD

AB = m + 6

CD = 3m + 2

BC = 3m

AD = 7m - 16

Since, ABCD is an isosceles trapezoid

so, two sides must be equal

now, we can plug values

now, we can solve for m

Divide both sides by -4

and we get
